Title: Improvements in or relating to caravans and like wheeled road-vehicles
IPC: B60P3/34
Filed: 1950-06-14
Abstract: 686,609. Caravan bodies; road vehicle under-carriages. DAVEY, J. June 14, 1951 [June 14, 1950], No. 14899/50. Classes 108 (i) and 108 (ii). A collapsable caravan has box-like side members 17, open at the tops and inner sides, pivoted longitudinally at 19, Fig. 1. Pairs of bell-crank levers 24 pivoted and held by chains 25 as shown, support U- shaped hood frame members 26, 30 and fabric 27 in the hood erected position. Sliding fasteners 28 provide a door flap, and where the gangway 16 emerges through the back of the body the gap can be closed by swinging up a footboard 29. The weight of the hood partially counterbalances the weight of the members 17 which are linked to move together by pivoted levers 31, 32, 33, Fig. 3, and in the collapsed condition the hood is complete contained within the upright members 17. Along the adjacent edges of the members 17 rubber strips are provided, and angle irons projecting at the tops of the adjacent vertical edges at the front and back of the folded caravan engage together by boss and socket means to prevent relative movement between the members 17 during transport. The rest bar 35, Fig. 2, carrying the footboard 29, when lowered to the ground moves a cam 47 against an abutment 52 on the carriage spring 48 to by-pass the spring and form a solid support for the caravan. The draw bar 38 pivoted at 39 engages manually releasable locking cams 41 when lifted up, and may also be lowered on side to form a support. The bar 38 when lowered to the ground is prevented from moving upwardly by a pivoted link 43 which has at its forward end a spring-loaded ring plate 44, the hole in which is only slightly larger than the bar passing therethrough. Only when the plate 44 is square with the bar will it be slidable therealong to release the bar. In the lowered position the spring 45 and the weight of the caravan force the plate 44 out of square to grip the bar, and only by moving the lever 46 to rock and square the plate may the bar be released and lifted. Instead of limiting stops 20, telescopic struts 51 employing hood tensioning springs may be used, and stops 34 are provided on the members 17 to prevent the fabric from contacting bedding 23.

Patent GB-570506-A (GB)
Title: Process for separating and utilising unsaturated hydrocarbons
IPC: C07C7/10
Filed: 1943-09-17
Abstract: Unsaturated hydrocarbons are separated from less unsaturated hydrocarbons by contacting with a solution of a silver salt in a phosphorus acid at a temperature not exceeding about 65 DEG  C. to form an extract phase and a raffinate phase.  Olefins may be separated from paraffins, diolefins from mono-olefins, and aromatics containing unsaturated side chains such as styrene from those with saturated side chains such as ethyl benzene.  Olefins may be removed from gasoline or from paraffinic fractions to be isomerized.  An isoparaffin-olefin charging stock for alkylation may be obtained by treating an olefin, normal and isoparaffin mixture with a phosphoric acid solution of silver phosphate, separating an isoparaffin from the raffinate phase, and contacting this with the extract phase.  The hydrocarbons are preferably first purified from sulphur compounds. The concentration of the phosphoric acid is generally above 50 and below 95 per cent and that of the silver salt as high as will dissolve therein.  Silver phosphate may be replaced wholly or in part by silver oxide, carbonate, nitrate, acetate, fluoride or sulphate. Pressure is generally sufficient to maintain the liquid phase.  The hydrocarbons are recovered by heating or reducing the pressure, in one or more stages, by extracting with a secondary solvent or by addition of water.  A butene-butane fraction is extracted in liquid phase with a phosphoric acid solution of silver phosphate, the separated raffinate phase being treated to recover the hydrocarbons which are fractionated to separate iso- and n-butane. The isobutane is contacted with the extract phase in a second extracter to give an isobutane-butene mixture which is passed to an alkylator containing a known alkylation catalyst, for example hydrogen fluoride at 10-95 DEG C.  The product is debutanized, and the alkylate refractionated to recover a gasoline fraction.  In Examples: (1) a solution comprising 20 per cent silver phosphate in 67.5 per cent phosphoric acid is used for separating n-butene from mixtures with n-butane at temperatures of 0 DEG , 30 DEG , 40 DEG  and 60 DEG  C.; (2) 30 per cent silver phosphate in 85 per cent phosphoric acid is used similarly at 30 DEG C.; (3) the same solution is used for extracting styrene from a mixture with ethylbenzene at room temperature; (4) the effect of varying the concentration of silver phosphate from 5 to 30 per cent is illustrated; (5) a butadiene, n-butene, n-butane mixture is extracted similarly at room temperature; (6) a butane-butene fraction is extracted at 38 DEG  C. and the extract phase contacted with isobutane to yield a 10 : 1 isobutane-butene mixture which is alkylated with HF at 38 DEG  C.

Abstract: 875,692. Levelling vehicle suspensions. DUNLOP RUBBER CO. Ltd. May 2, 1960 [May 6, 1959], No. 15464/59. Class 108(2). A levelling valve operating automatically to admit or exhaust fluid from a suspension system in response to changes of the load on a vehicle has a piston 34 movable in either direction from a neutral position in a liquidfilled cylinder 13, a passage from one end of the cylinder to the other for restricted fluid flow and means actuated by the piston 34 to operate inlet 25 and exhaust 26 valves, the said valves being operated only after the piston has travelled a predetermined distance from its neutral position. A lever actuated by load changes turns a shaft 38 causing a forked lever 39 to press against one or other of washers 41 or 42. Washers 41 and 45 are fixed on either end of a rod 43 movable axially inside the piston between limits set by stops 46 and the washer 42 is slidable on the rod 43 against a spring 44. In consequence of this and of the restricted fluid flow, the piston moves only slowly and does not move at all for transient displacement of the lever 39. An actuating lever 31 engages with'clearance in a notch 33 in the piston and extends through, and is pivoted about, an elastic seal 32 situated between the cylinder 13 and an air-valve chamber 14. The outer end of lever 31 protrudes between two grooved pins 30 which operate the inlet and exhaust valves 25 and 26. The valves 25 and 26 comprise fourpronged thimbles seated on springs 22 and 27 and carrying rubber pads 24 and 28 which can seal a delivery conduit 17 from the inlet pipe 15 or from an exhaust outlet 17 respectively. Another thimble 18 and pad 23 on the spring 22 serve as a non-return valve.
